You cannot expect the official Android 5.1 update from Samsung for Galaxy Note 4 anytime soon, as the company has just finished its rollout of Android 5.0, some 4-5 months after Google unveiled it. But that doesn’t mean you cannot get the opportunity to try the latest and greatest of Android OS in 5.1, especially when you’ve awesome community of developers who are burning their midnight oil to get you exactly what you are craving for right now: the Android 5.1 update, based on AOSP. Thanks to AICP team, your Galaxy Note 4 can be updated to 5.1 right away, if you are ready to do the necessary groundwork, which basically means installing a custom recovery like twrp first (link below in guide) and then flashing the AICP ROM.

First thing though is determining whether your version of Galaxy Note 4 is compatible with this Android 5.1 update or not. Well, only if your Note 4’s model no. is SM-G910F/G, you can try this ROM, otherwise not. Check it in Settings – About phone, or on Note 4’s box.

Of course, nothing beats an official OTA update from the OEM if you want all original features of the device that were marketed to you and supreme stability, but for sacrificing that for AICP, you’re in turn getting the stock Android UI as Google envisioned it, which is way, way more beautiful and exciting than Samsung’s Touchwiz custom UI.
